President Donald Trump speaks during a meeting about the federal budget in the Roosevelt Room at the White House in Washington, DC, February 22, 2017.

Even though President Donald Trump'sbudget blueprint does not mention Social Security and Medicare, the administration is not "dodging the issue" and Trump will keep his campaign promises on the programs, said Mick Mulvaney, director of the Office of Management and Budget.

"The president is absolutely going to keep the promises he made on the campaign trail," Mulvaney added during a press conference on Thursday.

Mulvaney said spending that impacts programs such as Social Security and Medicare was not addressed in this blueprint "because that's not what this budget is." He added that a blueprint like this that deals with "top-line spending numbers" would not include spending related to Social Security, Medicare and Medicaid.

"This is the discretionary part of the budget, half of which as you know is defense, the other half is everything else..." he said.
